Using ‘fminsearch’ to Minimize a Function Specified by a File with Extra Parameters

In this video we show 4 different ways to use/call Matlab’s ‘fminsearch’ function to perform unconstrained optimization.

Topics and timestamps:
0:00 – Introduction
2:23 – Defining function to be optimized
6:30 – fminsearch with a function specified by a file
10:17 – fminsearch with an anonymous function
13:13 – fminsearch with an anonymous function with extra parameters
19:13 – fminsearch with a function specified by a file with extra parameters

AA516: I am not the best at coding and these matlab videos have really helped me refine my skills to complete our desired tasks. Thanks again!

[rowellcastro]

AA516: Thanks for the useful lesson Professor! Your use of switch / cases in the script peaked my interest and I will definitely take advantage of that instead of using if(true/false) statements when making matlab scripts for future homework.

AA 516 - It's really cool that we get the same results even with four different ways by using ‘fminsearch’ function

[bsgove]

AE512: I always found optimization a really interesting field. It seems so adjacent to fields like machine learning, and I hope to learn more about that someday.

Thank you, another great video that came along at a perfect time, as I've been looking into this topic over the last two days....really appreciate the work you put into these Dr Lum.

Thank you very much for this video it helped me to understand the basics of how to call a function in Matlab, I think these can also be applied to other functions!!
P.S: "Where did I miss the parenthesis" ...This question is so common ahaha

AA516: Great video it is always nice to learn new Matlab techniques

AA516
Great lecture - in addition to fminsearch, I also learned a bunch of other Matlab skills for the first time, like "switch" and smart indent haha

Excellent video, thank you for putting this together. Also love your passion!

I used Case 4 extensively in a very useful application at work, and it's become a standard for us.

AA516: Great to see some use cases of fminsearch

[WalkingDeaDJ]

Jason-AE512: It suggests a practical tutorial focusing on MATLAB's 'fminsearch' function, specifically tailored for those looking to optimize a function defined externally with additional parameters. This could be highly beneficial for students or professionals needing a concise guide on enhancing computational methods in their projects.

[zaneyosif]

AE512: can definitely see the power of fminsearch!

[chayweaver.]

AE512: Useful to know this function exists for other optimization problems I have in my engineering career

[philipcasey]

AE512: Thanks for the refresher on this for 512.

[karimverelche]

thank you, sir. I have a question, I would like to find the errors in fitting parameters using Monte Carlo

[TheFamliy]

What would be advantages of fminsearch over lsqnonlin, and vice versus?

[yzhofxj]

Good Video! I jusst wonder how that would work out for an optimization of a simulink model.

[pedrocalorio]

Great video! Could you do a video on fmincon, or fgoalattain?

[williammillar]

Hi Christopher, excellent video. Thanks. Our of interest, what do you think of the optimisation functionality in mathematics ( minus simulink). I appreciate that MATLAB is primarily a numerical simulation model, as opposed to a symbolic one, but I'm curious at what point you'd switch over to MATLAB. Thanks W

I need ur help please in Simulink .. Please send me
